Abrasive cleaning implement



Jan. 19, 1960 s. P. ANDREWS ABRASIVE CLEANING IMPLEMENT Filed May 28.1958 INVENTOR. SARAH P. ANDREWS United States Patent 2,921,417 ABRASIVECLEANING IMPLEMENT Sarah Phyllis Andrews, Niagara Falls, NY. ApplicationMay 28, 1958, Serial No. 738,390 6 Claims. 01. 51-185) This inventionrelates to a cleaning article and more particularly to an abrasivearticle especially adapted for use in cleaning the surfaces of what arecommonly known as rubber erasers.

It is a common experience to find that the surface of a rubber eraserhas become smudged in use and therefore unfit for further use on cleansurfaces because the smudge will rub off and dirty the surface to whichthe eraser is applied.

Moreover, a rubber eraser without protection will gather dust orotherwise become unclean if left on a desk or in a drawer along withother articles commonly found in such places.

My invention affords protection for the eraser against the accumulationof dirt when it is not in use and also provides a ready means forcleaning the eraser, whether the need for such cleaning has arisenbecause of its use as an eraser or because of the accumulation of dustor dirt while not in use.

A clear understanding of my invention will be gained by reference to theappended drawing, in which:

Figure l is a perspective view of one embodiment of my invention;

Figure 2 is a sectional view along the line 2-2 of Figure 1; and

Figure 3 is a perspective view of the abrasive element of anothermodification of my invention.

In Figure 1 there is illustrated an abrasive article 1 comprising ashield 2 with an abrasive coated web 3 attached thereto by a wire staple4.

Figure 2 shows a paper board shield 2 with an abrasive coated web 3,comprising an open mesh backing 7 with abrasive particles 8 adhesivelyattached thereto, formed by folding a strip of the material upon itselfat the middle, held in a fold or crease 5 in said shield by means of awire staple 4. Other means than a wire staple can be used to attach theabrasive web to the shield; e.g. an adhesive may be used.

In Figure 3 there is illustrated an abrasive coated element 3 in whichthe web itself or the so-called backing 7 is of paper or cloth of theusual kinds and the abrasive particles 8 are attached to a surfacethereof.

The shield, for the sake of economy, preferably is made of light weightpaper board, but other materials, such as various well known sheetedplastics, may be used. The shield is made by taking a strip of paperboard, for example, of the correct width and length and forming atransverse crease 5 therein close to one end. Another crease 6 then isformed in said strip at a sufiicient distance from the first crease 5 toprovide an intervening space large enough to readily receive andaccommodate the abrasive element 3.

The abrasive element 3 can be made of a web of paper or cloth to whichabrasive granules of any desired size are adhesively attached. Oneparticularly desirable abrasive web is that which is made by adhesivelyattaching the abrasive granules to an open mesh or square weave cloth.In this modification the abrasive particles are attached to both sidesof the cloth and substantially enclose the threads of the cloth. Themethods by which the abrasive coated webs, including this open mesh web,are made are well known in the art.

To clean an eraser the flap 9 of the shield is opened to expose theabrasive coated web and that part of the surface of the eraser which isto be cleaned is rubbed against the abrasive particles until the dirt orsmudge has been removed. There being spaces between the abrasiveparticles in any case it is a simple matter to remove the detritus fromthe cleaner. The open mesh abrasive web is especially easy to cleanafter use.

Having thus described my invention, I claim:

1. An abrasive article comprising a web having abrasive granulesadhesively attached to a surface thereof, said web being in the form ofa strip folded upon itself at the middle and being fastened at the freeends thereof to and within a shield that covers both faces thereof andpermits of exposure of said web when desired.

2. An abrasive article comprising a strip of cloth having abrasivegranules adhesively attached to a surface thereof, said strip of clothbeing folded upon itself at the middle with the abrasive granules on theoutside and being fastened by the free ends to and within a shield thatcovers said strip and permits of exposure of said abrasive coatedsurface.

3. An abrasive article comprising a strip of open mesh cloth havingabrasive granules adhesively attached thereto, said strip of cloth beingfolded upon itself at the middle with abrasive granules on the outsideand being attached by the free ends thereof to a shield at one free endthereof and which shield is folded over both ends of said strip andwhose other free end projects to and beyond the first mentioned free endof said shield and can be tucked under said free end, whereby to enclosesaid abrasive coated strip.

4. An abrasive article comprising a strip of open mesh cloth havingabrasive granules adhesively attached thereto, said strip of cloth beingfolded upon itself at the middle with abrasive granules on the outsideand being attached at the free ends thereof to a fabric shield at onefree end thereof and which is folded over both ends of said strip andwhose other free end projects to and beyond the first mentioned free endof said shield, and can be tucked under said free end whereby to enclosesaid abrasive coated strip.

5. An abrasive article comprising a strip of open mesh cloth havingabrasive granules adhesively attached thereto, said strip of cloth beingfolded upon itself at the middle with abrasive granules on the outsideand being attached at the free ends thereof to a paper shield at onefree end thereof and which is folded over both ends of said stripandwhose other free end projects to and beyond the first mentioned free endof said shield, and can be tucked under said free end whereby to enclosesaid abrasive coated strip.

6. An abrasive article comprising a strip of open mesh cloth havingabrasive granules adhesively attached thereto, said strip of cloth beingfolded upon itself at the middle with abrasive granules on the outsideand being stapled at the free ends thereof to a paper shield at one freeend thereof and which is folded over both ends of said strip and whoseother free end projects to and beyond the first mentioned free end ofsaid shield, and can be tucked under said free end whereby to enclosesaid abrasive coated strip.
